'SPECIFICATION forming part of Letters Patent No. 545,360, dated August 27', 1895.

Application led August 31, 1894. Serial No. 521,835. (No model.)

To all whom may concern: tition-plat'e 7c and outwardly-projecting end Be it knownV that I, HARRY II. HIBBERD, a plates 7b, extending across the chamber and citizen ot' theUnited States, residingatWheel-- forming narrow passages 7d intermediate of ing, in the county of Ohio and State of West the tubes and the burner-openings and pock- 55 5 Virginia, have invented certain new and use-v ets 7 e beneath the end plates, the partitionful Improvements in Gas-Burners, of which plates and end plates dividing the mixingthe following is a specication. chamber into two parts, as shown, in order to My invention relates to burners for the cause a complete commingling of the air and consumption of gas as a fuel, and which are gas to produce the desired non -luminous 6o xo adapted both for heating and cooking purdame of complete combustion. rIhe tops of poses, my present invention consisting in the mixing-chambers are approximately obpart of certain improvements in burners emlong in shape.

The horizontal series of burners is provided with a supply-tube 4, having escape-openings 5 presented toward the open ends 3 of the tubes 1, as described with reference to Fig. 1, Whilethe upwardlypresented annular burners 8 have supplypipes 9 and 10. The pipes 4, 9, and 10 communicate with a common pipe 11, but each communicationis controlled by an independent valve 4@ 9L 10a. It thus 'becomes possible to utilize either burner separately, or any two or all of the burners at will. Referring to the series ofA urners, as shown in Fig. 1, such a form is preferable, inasmuch as it increases the facility for mixing the air and gas and at the same time causes the mixture to leave the outer ends of the tubes with greater force and to strike' the partitions in the mixing-chamber and effect a more thorough mingling.

For convenience in arrangement of the parts the series of burners has cast integrally with it brackets 2 for the various supplytubes, and a portion ot' tube l0 is attached end to end in the bracket to tube 9, said tubes be ing separated, however, bya plug 12, in order to keep separate the supply of gas to the re-.

' spective annular burners 8. Each annular burner 8 is supported upon and supplied by an upright auxiliary commingling-tube 8, screwed into the web of the group of integral burners, and beneath the lower open ends of those tubes S are upwardly-presented escape-openings 51L and 5b in the respective supply-pipes 9 and 10. Each of the auxiliary burners 8 has anhannular combustion-chamber 13, across the bottom of which extends a tube 13a, and from the upper portion of this combustion-chamber the gas escapes th rough inner and outer radial openings 7. The auxiliary burners may be connected indirectly by the side-couplings 13b and short pipe Sb with the auxiliary tubes or by means of the bottom couplings 13c directly to the auxiliary tubes, according to the distance apart of the fire-holes of the stove With which the burners are used, the coupling not in use being closed by a plug 13.

In arranging the above-described burner in the stove it is simply necessary to make openings to accommodate the supply-pipes 4, 9, and 10 and to properly support the burner at the right height in the fire-chamber ofthe stove, with the controlling-valves 4a, 9, and 10 exposed on the outside for convenience in manipulation.

A burner constructed as above described with reference to Fig. 1, or as described with. reference to Figs. 2, 3, and et, will be found to be Well adapted for burning either naturalor manufactured gas.

While I have described somewhat minutely the details in the construction of the burners, I do not limit myself to these precise constructions.

Having thus described my invention, the followingis what I claim as new therein and desire to secure by Letters Patent:

1. A gas-burner comprising a commingling tube and a spreading semi-circular chamber 6 formed with yan approximately oblong top having a ser-ies of burner-openings 7, with a central transverse partition-plate 7, and with outwardly projecting lend plates 7b, extending across the mixing ychamber and providing narrow transverse passages 7d intermediate of the tubes, and the burner-openings, and pockets 7e located beneath the end plates;

the partition-plates and the end plates dividing the mixing chamber into two parts, substantially as described.

2. vA gas-burner comprising a spreading Semi-circular chamber 6 formed with an approximately oblong` top having a series ol' burner-openings 7, with a central transverse partition-plate 7, and with outwardly projecting end plates 7b, extending across the mixing chamber and providing narrow transverse passages 7 intermediate of the tubes andthe burner-openings, and pockets 7e located beneath the end plates, and a comminglingv tube tapered toward the partition-plato for directing the flow of mingled air and gas onto the center thereof; the partition-plate and the end plates dividing the mixing chamber into two parts, substantially as described.

3. A gas-burner comprising a supporting rack 2 having end brackets 2a the supply pipe 4:, the horizontal commingling tubes and mixing chambers, the vertical commingling tubes and mixing chambers, the plugged supply pipe 9 communicating with one of the vertical commingling tubes, the' supply pipe 10 supporting the inner end of the plugged pipe and communicating with the other vertical commingling tube and the main pipe common to all the supply pipes having independent valves for the supply pipes; substantially as described.
